Chemical Energy Energy stored in the bonds of chemical compounds.
Radiant Energy Energy of electromagnetic waves.
Chlorophyll A green pigment found in plants that they use with light to make food.
Glucose A simple sugar mainly made by plants during photosynthesis from water and carbon dioxide, using energy from sunlight.

Positive Tropism The organism moves toward the stimulus.
Stimulus A detectable change in the internal or external environment of an organism.
External Stimulus Stimulus from outside the organism.
Internal Stimulus Stimulus from within the organism.
Response Any change an organism makes because of a change in he environment.
Turgor Pressure The pressure that water-filled vacuoles exert on the cytoplasm and the elastic cell wall in a plant.
Wilting Water moves out and the plant cells and causes them to become more concave and the plant will loose its rigidity.
Osmosis Water moves in and out of a plant cell through the cell wall.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
